[Bug 35341] Re: Panels sometimes appear over locked screen

[Brendan Martens]

I have recently had a big of enlightenment on this bug, I think. I seem
to only have this problem when beryl is active, is that so for anyone
else? Can anyone confirm that? If so we can close the bug again, because
it'd be a beryl issue, I believe.
